Answer:
30kg
Explanation:
Distance between Alok and father = 5m
Father's distance from fulcrum = 2m
Solak's weight = 20kg
Unknown:
Weight of the father = ?
Solution:
This problem entail the balancing of forces around a fulcrum.
In this problem;
workdone by father = workdone by Alok
( mass x distance) father = (mass x distance) Alok
distance of Alok from the fulcrum = 3m
Input the parameters and solve;
mass of father x 2 = 20 x 3
mass of father = 30kg
The weight of the father is 30kg
